>> we have to be very creative here because there are lots of people who have that piece of pap e they may have a passport or visa or have everything but they may not want to bring it with them through taliban check points because if the taliban find that american piece of paper, they're on the taliban's list. right? and so but we know who these folks are. we know their phone numbers. that's another way of identifying people. there may be other creative ways as we contact people to ask them to come to the airport to give them something that isn't obvious to the taliban but may allow our people at the gate to identify them. that's going to take a few days to set up that system and get control of that gate. another reason why there can't be a deadline. >> you were critical of the biden administration's decision to withdraw all u.s. troops. you thought there should be a remaining presence there, at least for some time. it happened. it's done at this point. although now u.s. has more troops in than we did than the united states did a short time
